DEVICE FOR CLEANING THE WATER-TTGHT BLANKETS OF CLOTH-PBINTING MACHINES.

' Specification of Letters Patent.

Patented July 19, 1910.

Application filed-September 21, 1809. Serial No. 518,885.

To all whom it may concern:

Be it known that I, FRANZ XA'VER MUL- Lax-FIGHTER, a subject of theGerman ,Em-

eror, and resident of Thann i., Alsace, ermany, have invented certainnew and useful 1m rovements in Devices for Cleaning the ater-TightBlankets of Cloth- Printing Machines, of which the following is a full,clear, and exact'description.

he present invention relates to a device for cleaning thecounter-pressing rollers, of

cloth-printm -machines and consists in the substitution or the ordinarywatertight covering of such rollers of an endless watertight blanketguided on rollersL Instead of and drying aprons ordinarily used forcleanin the counter-pressing roller, said blanketis itself, after'eachim ression, passed through a system of washing and cleaning rollersand thereupon subjected to a drying process before it again comes intocontact with the counter-pressing roller.

The advanta e of the invention is that the endless was ing blanket beingmade of watertight, tough material is far more easy to guide on itsrollers than are the soft-wiping and drying a rons which easily getd1splaced and there ore require frequent ada more thorou h cleaning ofthe blanket will be efiecte by the present inventlon, than is t e casewhen using wiping and drying aprons.

In the accompanyijfg drawinga sample 85 .form of construction of theimproved arra ement is shown in a dlagrammati'c view.

' ing-machine ecounter-pressing roller l of the printreceives a coverin"a which consists of an endless watertigfi I running-on, guide-rollers bfrom and to the counter-pressing roller. This blanket is first washed ymeans of a roller g over which a spra pipe 1 is arranged. It is thenwiped y a rub er or'felt roller 11 which 'rotates in a directionopposite to that'of the blanket and which is, mits turn, cleaned b p abrush-roller f and a squeezing-roller passed. the rollerithe blanket isnext sub ected to the 'action of a scraper k Having which completes thecleaningof the same.

. It is thereupon conducted under'a felt covered roller p, .by which itis preliminarily with a rotating wipin tubes m blanket cleaned and driedit means of a series of perforatedpipes we producing a hot air currentthrou h which the blanket passes. In order to re uce thetemperatureimparted by the hot air current to the blanket, the latterissubsequently conducted over a series of pipes duce a cold air current.I thus dispense band device. and ac n which pro-v complish a more relia1e and perfect cleaning of the blanket and more result in the printing.

-The process of cleaning1 the dirty blanket during the printing is t efollowing: The endless blanket a passes durinfithe printing around thecounter-pressing r0 tween the latter and the fabric to be printed.Having passed the printing rollers, the blanket is conducted'to the ccaning device where the color-adherin to it is first damped by therollers g and .t en removed by the roller 2'. The brush roller workingin o posite direction to the ro er 2', washes t e color off the latter,and the water adhering.

final cleamn of'the blanket is effected by the scraper After the blanketa has in thisway been cleaned, the drying-process commences, whichconsists in' causing the felt covered drying-cylinder p, to-rubofi theblanket a whereupon the latter for the purpose of being thoroughly driedpasses over guide-rollers 6 along the system of provided with nozzlesthroughwhich a hot air current emanates. The system tubes n, along whichthe blanket'is subsequently conducted, eflects the cooling of the same.After the blanket has been thus again passes around the counter-pressingrol er I. p v 4 A device for cleaning the water -tight hblankets ofcloth printing machines, com.-
